Quizplus · Accepted Answer

Posner's precueing studies showed that attention acts as a spotlight that enhances the efficiency of processing information, allowing for faster reaction times and improved accuracy. This suggests that attention increases the effectiveness of information processing rather than perceptual abilities such as color perception or the ability to detect changes in a scene. The studies also demonstrated that attention can be directed to specific objects based on cues, thus indicating that it can be focused and directed rather than spreading uniformly through a scene.
